Partial Derivatives Dialog

Select the partial derivative event for which you wish to calculate partial derivatives. The partial derivative(s) of the probability of the selected event will be calculated.

With Respect to (leave blank for all)

If you are interested in the partial derivative of the selected event with respect to a particular variable, select it from the drop-down list. The result will be written to the Session Log.
If you would like DPL to calculate the partial derivatives of the selected event with respect to all variables, leave this blank. A Partial Derivative chart will be created.
Results will also be written to the log.

If the fault tree has time series defined, specify the time period for which you'd like partical derivatives.

Sort By

Select how you would like the output sorted. You may sort by either the absolute value of the partial derivative or the maximum impact on the selected event.
